Problems solved by technology

[0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology utilizes high temperature heat load to drive heat supply or cooling; big limit
Compression heat pump technology that utilizes the grade difference between mechanical energy and thermal energy has certain flexibility, but in many cases it is difficult to achieve efficient utilization of thermal energy
At the same time, the two technologies also have a common deficiency - they cannot convert thermal energy into mechanical energy while heating or cooling

Abstract

The invention provides a first-type thermally driven compression heat pump, and belongs to the technical field of power, refrigeration and heat pumps. A circulating working medium channel of a compressor communicates with an expander by a high-temperature heat exchanger; a circulating working medium channel of the expander communicates with a second expander by a heat supplier; a circulating working medium channel of the second expander communicates with the compressor by a low-temperature heat exchanger; a working medium channel at the external communicates with a second compressor; a workingmedium channel of the second compressor communicates with a third expander by a second high-temperature heat exchanger; a working medium channel of the third expander communicates with the external by a high-temperature heat exchanger; a heated medium channel of the heat supplier communicates with the external; a low-temperature heat medium channel of the low-temperature heat exchanger communicates with the external; a high-temperature heat medium channel of the second high-temperature heat exchanger communicates with the external; and the expander, the second expander and the third expanderare connected with the compressor and the second compressor, and transmit power to form the first-type thermally driven compression heat pump.

Description

Technical field: [0001] The invention belongs to the technical field of power, refrigeration and heat pump. Background technique: [0002] Cold demand, heat demand and power demand are common in human life and production; in reality, people often need to use high-temperature heat energy to achieve cooling, heating or conversion into power, and also need to use power for cooling or use power combined Low temperature thermal energy for heating. In the process of achieving the above goals, there will be many considerations or constraints, including the type, grade and quantity of energy, the type, grade and quantity of user needs, ambient temperature, type of working medium, equipment flow, structure and Manufacturing costs and more. [0003] Thermal energy (temperature difference) utilization technology represented by absorption heat pump technology utilizes high temperature heat load to drive heat supply or cooling; big limit. Compression heat pump technology, which utili...
